INTRODUCTION The U.S. Geological Survey's investigations of the water resources of Texas are conducted in cooperation with the Texas Water Development Board, river authorities, cities, counties, U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, Interna­ tional Boundary and Water Commission, and others. Investigations are under the general direction of C. W. Boning, District Chief, Texas District. The Texas District office is located at 8011 Cameron Road, Bldg. 1, Austin, Texas 78753. Information regarding hydrologic data collected within their respective areas may be obtained from the subdistrict offices listed below: W.E. Reeves, Chief J.H. Eade, Subdistrict Chief Field Headquarters U.S. Geological Survey, WRD U.S. Geological Survey, WRD 1409 Knickerbocker Road 300 E. 8th Street, Federal Bldg.

Houston, Texas 77004 Wichita Falls, Texas 76301 As of January 1, 1988, the surface-water data-collection network in Texas in­ cluded 368 continuous streamflow, 12 continuous or daily reservoir-content, 38 gage height, 15 crest-stage partia 1-record, 4 periodic discharge through range, 32 flood- hydrocjraph partial-record, 9 flood-profile partial-record, 36 low-flow partial-record 45 daily chemical-quality, 19 continuous-recording water-quality, 83 periodic bio­ logical, 19 lake surveys, 160 periodic organic and (or) nutrient, 3 periodic insecti­ cide, 33 periodic pesticide, 20 automatic sampler, 137 periodic minor elements, 125 periodic chemical-quality, 74 periodic physica1-organic, 24 continuous-recording three- or four-parameter water-quality, 34 periodic sediment, 21 continuous-recording temperature, and 30 national stream-quality accounting network stations. Plate 1 shows the location of surface-water streamflow or reservoir-content and chemical- quality or sediment stations in Texas. Plate 2 shows the location of partial-record surface-water stations. This index shows the station number and name, latitude and longitude, type of data collected, and the office principally responsible for the data collection (table 1). An 8-digit permanent numerical designation for gaging stations has been adopted on a nationwide basis; stations are numbered and listed in downstream order. In the downstream direction along the main stem, all stations on a tribu­ tary entering above a main-stem station are listed before that station. A tribu­ tary entering between two main-stem stations is listed between them. A similar order is followed in listing stations on first rank, second rank, and other ranks of tributaries. To indicate the rank of any tributary on which a gaging station is situated and the stream to which it is an immediate tributary, each indention in the listing of gaging stations represent one rank. This downstream order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated. On plates 1 and 2, the 8-digit station number is abbreviated because of space limitation.

-1- DEFINITION OF TERMS CONTINUOUS-RECORDING CONDUCTIVITY STATION is a water-quality station at which a continuous record of specific conductance is obtained by a conductivity monitor. For each of these stations where discharge records (see CONTINUOUS STREAMFLOW STA­ TION) are available, discharge-weighted-average concentrations and loads of selected chemical constituents are computed using the continuous record of specific conduct­ ance and regression relationships between each chemical constituent and specific conductance. CONTINUOUS-RECORDING THREE- OR FOUR-PARAMETER WATER-QUALITY STATION is a water- quality station at which continuous records of specific conductance, temperature, dissolved oxygen, and pH are obtained by a water-quality monitor. For each of these stations where discharge records are available, discharge-weighted-ayerage concentrations and loads of selected chemical constituents are computed using the continuous record of specific conductance and regression relationship between each chemical constituent and specific conductance. CONTINUOUS-RECORDING TEMPERATURE STATION is a water-quality station at which a continuous record of water temperature is obtained by a temperature monitor. At each CONTINUOUS OR DAILY RFSERVOIR-CONTENT STATION, a daily record of stage is obtained from which a daily value of content (usually at 2400 hours) is computed, compiled, and published. At each CONTINUOUS STREAMFLOW STATION, a permanent gage is maintained from which a continuous record of stage is obtained. Measurements of flow are made to develop stage-discharge relations. Discharge records, showing the mean daily dis­ charge and peak discharges for the major floods of each year, and total monthly and yearly runoff expressed in inches and (or) acre-feet, are computed, compiled, and published on the basis of the water year ending September 30. DAILY CHEMICAL-QUALITY STATION is a water-quality station at which samples are collected and specific conductance and water temperature are measured once daily or more frequently. For each of these stations where discharge records are available, discharge-weighted-average concentrations and loads of selected chemical consti­ tuents are computed using the daily record of specific conductance and regression relationship between each chemical constituent and specific conductance. GAGE-HEIGHT STATION is a site where only the water-surface elevation, referred to some arbitrary gage datum, is collected. LAKE SURVEYS are a comprehensive water-quality data-collection program on selected reservoirs in the State. Each reservoir will have three or more primary sites and any number of secondary sites. Field measurements of dissolved oxygen, temperature, specific conductance, and pH are made at 5- or 10-foot intervals at each primary and secondary site. In addition, major inorganic constituents, nutri­ ents, and selected minor elements are collected from near the surface and near the bottom of all primary sites. During periods of thermal stratification, additional nutrient samples and samples for the determination of dissolved iron and dissolved manganese are collected just above and below the thermocline of primary sites. NATIONAL STREAM-QUALITY ACCOUNTING NETWORK (NASQAN) is a USGS data-col 1ection network designed to (1) depict areal variability of streamflow and water-quality conditions nationwide on a year-by-year basis and (2) detect and assess long-term changes in streamflow and water quality. PERIODIC BIOLOGICAl STA1ION is a water-quality station where samples are col­ lected periodically (usually from 3 to 6 samples per year) and analyzed for the densities of fecal coliform and fetal streptococcal bacteria and (or) phytoplank- ton. PERIODIC CHFMICAl-QUAlIIY STATION is a water-quality station where samples are collected periodically (usually from 2 to 10 samples per year) for the analy­ ses of major inorganic constituents and related properties. Most of these sta­ tions on streams are operated in conjunction with a stream-gaging station; and an attempt is made to collect samples over as wide a range in discharge as possi­ ble. Some of these stations are equipped with stage-activated AUTOMATIC SAMPLERS to facilitate the collection of several samples during periods of storm runoff. Samples from stations on reservoirs usually are collected seasonally during com­ prehensive lake surveys.

-2- PARTIAL-RECORD STATION. Because the number of streams for which information is desired far exceeds the number of stations feasible to operate for continuous record, the Geological Survey collects limited streamflow data at other stream- gaging sites. When limited streamflow data are collected on a systematic basis over a period of years for use in hydrologic analyses, the site at which the data are collected is called a PARTIAL-RECORD STATION. There are four basic types of part ial -record stations: (1) A fl ood-hydrograph parti al -record station is oper­ ated for the purpose of defining stages and maximum discharges during flood peri­ ods; (2) crest-stage part i al -record station is operated for the purpose of defin­ ing annual maximum stages and discharges; (3) low-flow parti al -record station is operated for the purpose of defining annual minimum discharges; and (4) reconnais­ sance part i al -record station is operated to cover a range of discharge and the corresponding variation in water quality. Discharge measurements at low-flow part ial -record stations are usually made during the periods of base flow when streamflow is primarily from aquifers. PERIODIC INSECTICIDE STATION (BOTTOM SEDIMENTS) is a site where samples of bottom sediments are collected periodically (usually from 1 to 3 samples per year) and analyzed for selected organochlori ne or other insecticides and related industrial compounds. PERIODIC MINOR ELEMENT STATION is a water-quality station where samples are collected periodically and analyzed for minor elements such as arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, selenium, silver, and zinc. Analyses of minor-element samples collected from most of the reservoir stations include only iron and manganese. The number of samples collected from stations on streams usually range from 2 to 4 per year. Reservoirs are usually sampled seasonally during comprehensive lake surveys. PERIODIC-ORGANIC AND (OR) NUTRIENT STATION is a water-quality station where samples are collected periodically and analyzed for properties or constituents such as biochemical oxygen demand (BOD), dissolved oxygen (DO), pH , and nitrogen and phosphorus species. The number of samples varies from station to station but usually ranges from 3 to 9 samples per year. PERIODIC PESTICIDE STATION (WATER) is a water-quality station where samples are collected periodically (usually from 2 to 4 samples per year) and analyzed for selected pesticides such as carbonate, organochl or ine, or organophosphorus insecti­ cides and chlorophenoxy acid or triazine herbicides. PERIODIC PHYSICAL ORGANIC SFAIION is a water-quality stati9n where samples are collected periodically and analyzed for properties or constituents such as color, turbidity, suspended solids, volatile suspended solids, and total organic carbon (TOC). The number of samples varies from station to station but usually ranges from 3 to 9 samples per year. PERIODIC SEDIMtNl SIAflON is

AVAILABILITY OF DATA Most of the information and data collected f9r the various types of stations listed above are computed, printed, a ,d released in an annual publication, "Water Resources Data, Texas, Volume 1. Arkansas River Basin, Red River Basin, Sabine River Basin, Basin, Basin, and Intervening Coastal Basins"; "Water Resources Data, Texas, Volume 2. San Jacinto River Basin, Basin, Basin, and Intervening Coastal Basins"; and "Water Resources Data, Texas, Volume 3. Basin, Basin, Guada- lupe River Basin, Basin, Basin, and Intervening Coastal Basins". These volumes are for limited distribution and are published primarily for the rapid release of data shortly after the end of the water year. Copies may be purchased from the Books and Open-File Reports Section, Branch of Distribution, U.S. Geological Survey, Box 25425, Federal Center, Denver, Colorado 80225 (phone (303) 236-7476].

-3- The International Boundary and Water Commission, and , operates most streamflow and some chemcal-quality stations on the Rio Grande and near the mouths of its principal tributaries at and below El Paso, Texas. Dis­ charge records collected at these stations are published in annual bulletins by the Commission and may be obtained by addressing your request to the International Boundary and Mater Commission, United States Section, Commons Building C, Suite 310, 4171 N. Mesa, El Pas9, Texas 79902. Some qua 1ity-of-water samples are collected by the International Boundary and water Commission and analyzed by the Geological Survey. These records are also published by the Geological Survey in the annual series of WATER RESOURCES DATA, TEXAS. In addition to hydrologic information collected at established gaging sta­ tions, measurements of streamflow and water-quality data have been obtained for specific purposes at other locations in the State. Many of these measurements show the peak discharge for unusual floods, while others show minimum flows or channel losses, gains, and change in water quality in various stream reaches. Water-supply papers and other reports containing special detailed informa­ tion on flood discharges, rainfall intensities, hydrology of small watersheds, pollution by naturally occurring saltwater, and other related data have been prepared by the Geological Survey. In addition to published reports, records not yet published and file copies of special reports on floods and other investi­ gations are available for examination in the District and Subdistrict offices (see p. 1) of the Geological Survey in Texas.
